Production technology of small weighing sensor

Abstract

The invention discloses a production technology of a small weighing sensor, and belongs to the technical field of sensor production. The production technology comprises procedures of grinding and scribing, surface-mounting, bridging and wiring, temperature compensation, welding, sealing of surface mounted holes, preliminary welding, re-measuring, sealing of compensation holes, final welding, cleaning, warehouse entry inspection and packaging. Patterns and an electroplating layer generated during processing of an elastomer are ground off, a reference line during surface mounting is drawn, a sensitive component is pasted to an elastic component, a strain gauge is connected to, a temperature compensation technology is carried out, a lead is welded to a circuit board, the surface-mounting and compensation holes of the sensor are sealed, the lead is welded to the circuit board, different indexes of a product are detected, the surface-mounting and compensation holes of the sensor are sealed, the lead is welded to the circuit board, the metal elastomer is cleaned, different parameters are tested, and the product is warehoused and classified when satisfying the requirement. According to the production technology of the small weighing sensor, the pasting position of the strain gauge is accurate, the sensitivity of the sensor is high, and output satisfies specific requirement.

Description

technical field [0001] The invention relates to the technical field of sensor production, in particular to a production process of a small weighing sensor. Background technique [0002] With the rapid development of industry, the application of electronic weighing sensors in industry is becoming more and more extensive. The traditional production process is manual patching. Accurate, low sensor sensitivity, large errors in electrical signal input and output, volatile cleaning agent, difficult to reuse, and serious waste, so design a patch area with high surface accuracy, the sticking position of the strain gauge is accurate, and the sensor has high sensitivity. The signal is effectively input and output, and the production process of the small load cell that the cleaning agent can be reused is very necessary. Contents of the invention [0003] The purpose of the present invention is to overcome the microscopic unevenness of the surface of the patch area, inaccurate sticki...
